A Method to Slow or Stop Electromagnetic Waves for Use in Optical and Microwave Communication Systems
Northeastern University
posted on 05/01/2009
The invention describes a waveguide that can slow or stop electromagnetic waves. This waveguide can be used from microwave up to ultraviolet frequencies, and is designed to slow and trap light.
Suggested Uses
• Optical communication systems
• Microwave communication systems and devices
• Ultra-compact optoelectronic devices
• Optical buffer for integrated photonic circuits
• Semiconductor heterostructures
• Delay line elements in microwave range
Advantages
• Increased ease and simplicity of fabrication
• Decreased materials requirements
• Increased ability to trap light
• Greater device performance
• Lower loss (compared to double negative-index materials)
• Low power consumption
• Increased efficiency of optical nonlinear processes
Detailed Description
The invention is made up of a tapered waveguide clad with a single negative material that slows or stops electromagnetic waves. This waveguide can be used from microwave up to ultraviolet frequencies, and is designed to slow and trap light.
The ability to slow or stop light is crucial for the realization of all-optical integrated circuitry. The proposed structure is simpler to achieve than the current standard (double negative metamaterials), has a small footprint, and can be incorporated into ultra-compact on-chip optoelectronics. Analytical results have been confirmed by FDTD simulations.
